The Qtopia cross-development toolchain that Trolltech supplied to
entrants in the Zaurus competition.
As you know Qt/E can be built in many different ways with different
classes included or not depending on what the designer of the system has
to work with. It's quite possible (even likely) that the Qt/E for the
Zaurus is incompatible with the Qt/E for the iPAQ. However, the same
PyQt/E source should compile on both because it's clever enough to
handle the different features that have been enabled or disabled.

I think you need to re-compile - but are you saying that there isn't a
cross-development toolchain for the iPAQ? I would question the sanity of
anybody using a PDA as a software development environment.
